What would your proof be? All quantum field theories are Lorentz-invariant
(so the same laws apply in different reference frames with different
definitions of simultaneity), although this refers only to the equations
governing the dynamics of the fields in between measurements. The
measurement process itself is still somewhat mysterious, so perhaps some
interpretations of QM would say that it violates Lorentz-invariance, like
Bohm's interpretation (although Bohm's interpretation has never been
successfully extended from nonrelativistic quantum mechanics to relativistic
quantum field theory) or certain variations of the Copenhagen
interpretation. But I don't think any version of the MWI would say that
measurement introduces a preferred reference frame.
